Login architecture question

Hi there,

I'm implementing a login functionality in my app and have some difficulties with architecture. Could you guide me what is a good practice for such tasks?

In the main Scene I show MainView or LoginView based on factory.isAuthorized

import SwiftUI

@main
struct TestApp: App {

    @StateObject var factory = MyFactory()

    var body: some Scene {
        WindowGroup {
            if factory.isAuthorized {
                MainView().environmentObject(factory)
            } else {
                LoginView().environmentObject(factory)
            }
        }
    }
}

In the factory ObservableObject I have a saveSession func. It changes isAuthorized to true in the end.

final class MyFactory: ObservableObject {

    @Published var isAuthorized: Bool = false

    func saveSession(session: String) {
        // here some code
        isAuthorized = true
    }

The next piece is LoginViewModel. The login func does a HTTP request, gets response and passes token to the completion handler.

class LoginViewModel: ObservableObject {

    func login(email: String, password: String, completion: (String)->Void) {
        // run http request
        // read response
        completion("here is token from server")
    }
}

The final piece is my LoginView where I have a buton "Login" that calls model.login func and then passes token to my factory.

Button(
    action: {
        model.login(email: username, password: password) { session in
            factory.saveSession(session: session)
        }
    },
    label: {
            Text("Login")
    }
)

What do you think about that implemetation?

Thank you
